Hi all,
I have a resistance heater powered by a lithium ion battery, nominal 3.7 volts. This draws up to 10 amps. I want to add a PTC fuse to protect the battery in the event it was shorted. I can't find any info on what the trip current should be to protect against a short.
I picked this one RHEF1500HF-ND (https://www.digikey.com/product-detail/en/littelfuse-inc/RHEF1500/RHEF1500HF-ND/5029799) the hold current is 15A and the trip current is 28A. My guess is the trip current is too high with this one.
Any help would be greatly appreciated. Thanks for looking
